LAWS OF MANU
105. A guest who is sent by the (setting) sun in the evening, must not be driven
away by a householder; whether he have come at (supper-) time or at an inopportune
moment, he must not stay in the house without entertainment.
106. Let him not eat any (dainty) food which he does not offer to his guest; the
hospitable reception of guests procures wealth, fame, long life, and heavenly bliss.
107. Let him offer (to his guests) seats, rooms, beds, attendance on departure
and honour (while they stay), to the most distinguished in the best form, to the lower
ones in a lower form, to equals in an equal manner.
108. But if another guest comes after the Vaisvadeva offering has been finished,
(the householder) must give him food according to his ability, (but) not repeat the Bali
offering.
109. A Brahmana shall not name his family and (Vedic) gotra in order to obtain a
meal; for he who boasts of them for the sake of a meal, is called by the wise a foul
feeder (vantasin).

Taittiriya Upanishad, Shikshavalli I.20
The five steps from the worship become the five formalities to be observed
while receiving guests:
1. Fragrance (Dhupa) - While receiving guests the rooms must have a
pleasant fragrance, because this is the first thing that attracts or detracts
